ABSTRACT:
A passenger car sized pendulum is supported by a moving pivot point. The moving pivot point is forced horizontally by the angular movement of the pendulum. By resisting the horizontal force the angular movement of the pendulum is reduced. The preferred embodiment for resisting the horizontal force is a parallelogram assembly supporting a horizontal support platform. The parallelogram assembly has a damping cylinder resisting the horizontal force.
